摘要:
A cell design and methods for reducing the cell size of cells in high-current devices, such as MRAM, by increasing the effective width of a transistor in the cell to be greater than the actual width of the active area of the cell are described. This permits the cell size to be decreased without decreasing the current that is driven by the transistor. According to the invention, this is achieved by increasing the length of gate portions of one or more transistors within the active area of a cell to increase the effective transistor width. In one embodiment, two transistors, electrically connected in parallel, are used per cell. The two transistors double the effective transistor width within the cell relative to a single transistor design. Such cell designs can be used with a variety of devices, including various types of MRAM and PCRAM.
